Revamping the numerous kitchens of a mine using specialised products that can withstand heavy foot traffic and several other elements.
When Western Goldfields Mine, south of Johannesburg, decided to revamp its numerous kitchens, Sika’s Chad Tosen recommended two high-performance products from Sika’s PurCem range for the floors and walls.
The first phase of the project commenced in October 2014 and was carried out by contractor Epoxy Coaters. Sikafloor-161 was applied as a primer on the deteriorated floors as it is an economical, two-part, solvent-free, low-viscosity epoxy resin that provides excellent penetration and bond strength. It is also easy to apply, with short waiting times, and suitable for use on normal to strong absorbent substrates.
This primer was followed with a 6 mm application of Sikafloor-20N PurCem, a three-part, resin-rich, water-dispersed, smooth-trowel-grade, polyurethane-modified, cement-and-aggregate screed that is suitable for floors subject to heavy loading, abrasion and chemical exposure. Its textured aggregate surface provides medium to heavy profile slip resistance.
Furthermore, the fluid consistency of Sikafloor-20N PurCem requires less labour to install than conventional heavy-duty, modified-PU, trowel-grade screeds and it is fast-curing – a critical factor when a project takes place in a working environment.
Concerning contact with foodstuffs, PurCem products conform to numerous international requirements, and are resistant to a wide range of organic and inorganic acids, alkalis, amines, salts and solvents. They are also non-taint, odourless and VOC-free, provide a high mechanical resistance and, when subjected to impact, will not deform or crack. All of the above factors make a PurCem product the ideal product for a kitchen environment.
Sika will be supplying its top-quality products for the second phase of this project, which is scheduled to commence in late November and should be followed by several more kitchen revamps in the coming months.
